Find the perimeter of the circle is the same as finding the circumference of the circle.

Circumference Formula: C = 2πr

Divide the diameter by 2 to find the radius.

7 / 2 = 3.5

Solve using the given values.

C = 2(3.14)(3.5)

C = 2(10.99)

C = 21.98

Therefore, the circumference (perimeter) of the circle is 21.98cm²

Best of Luck!
